what are the specific weight, density and specific gravity of one litre of a liquid which weighs 7N

Detailed Solution:

1- specific weight = weight/volume = 7N/(1/1000)cum = 7000 N/cum 2- density = specific weight / acc due to gravity = 7000 / 9.81 = 713.5kg/cum 3- specific gravity = specific weight of liquid/ specific weight of water = 713.5/1000 = 0.7135
